Will a Taurus Man fight for a woman?

Well, I know this Taurus man that really liked this Pisces woman but she didn't like him back so he gave up for a while. Then, he decided to try again, and he still is fighting to get her. Truth is, she tells me how he's extremely annoying and doesn't understand that it's never going to happen. And yes, it bothers him when other guys try to get her and he has to know everything about what he does with other guys. I don't think stubborn Taurus will give up that easily.
